Renesas R5F5631EDGFP#V0

Overview

R5F5631EDGFP#V0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 512 KB on-chip flash memory, 64 KB SRAM, 32 KB data flash, IEEE-754 single-precision FPU, and integrated 12-bit/10-bit A/D converters. It supports USB 2.0 full-speed host/function, CAN (2 channels), up to 13 SCI interfaces, I²C (4 channels), and operates from a 2.7–3.6 V supply across –40 to +85°C - used in industrial HMI and networked sensor gateway designs.

For engineers reviewing the R5F5631EDGFP#V0 datasheet, R5F5631EDGFP#V0 pinout, R5F5631EDGFP#V0 application, or R5F5631EDGFP#V0 equivalent, key selection considerations include its RX631 Group identity (no Ethernet MAC), LQFP-100 package with 78 GPIOs, 5-V-tolerant pins, and support for IEC60730-compliant safety functions including CRC, self-diagnostic A/D, and oscillation-stop detection.

Technical Context

The R5F5631EDGFP#V0 implements the CISC Harvard-architecture RX CPU with 5-stage pipeline, variable-length instructions, and MPU support. It executes at 165 DMIPS @ 100 MHz and integrates dual multiply-and-accumulate units plus a 32-bit multiplier completing one-cycle operations.

Its peripheral set excludes Ethernet MAC and SDRAM controller (distinguishing it from RX63N), but includes full-speed USB 2.0 OTG/host/function, CAN v2.0B (2 modules × 32 mailboxes), and parallel data capture unit (PDC) compatible with 512 KB flash variants - confirmed for this 100-pin LQFP configuration per Table 1.2.

FAQ

What is the maximum operating frequency and core type of the R5F5631EDGFP#V0?

The R5F5631EDGFP#V0 operates at a maximum frequency of 100 MHz using the 32-bit RX CPU core. This core delivers 165 DMIPS performance and includes a single-precision IEEE-754 floating-point unit, two multiply-and-accumulate units, and a 5-stage pipeline. Its architecture supports deterministic real-time execution critical for industrial control loops and USB/CAN protocol timing - all verified in the R01DS0098EJ0180 datasheet for the RX631 Group.

Does the R5F5631EDGFP#V0 include an Ethernet MAC controller?

No, the R5F5631EDGFP#V0 does not include an Ethernet MAC controller. It belongs to the RX631 Group, which explicitly excludes Ethernet functionality - unlike the RX63N Group. This distinction is confirmed in Table 1.2 of the R01DS0098EJ0180 datasheet, where "Ethernet controller" is marked "Not available" for all RX631 packages, including the 100-pin LQFP variant of R5F5631EDGFP#V0.

What memory resources are integrated into the R5F5631EDGFP#V0?

The R5F5631EDGFP#V0 integrates 512 KB of on-chip flash memory (zero-wait-state at 100 MHz), 64 KB of SRAM, and 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles. These resources are fixed for this part number per Table 1.3 in R01DS0098EJ0180 and support background programming/erasing (BGO) for firmware updates without halting application execution.

Which communication interfaces are supported by the R5F5631EDGFP#V0?

The R5F5631EDGFP#V0 supports USB 2.0 full-speed host/function/OTG (1 port), CAN (2 modules, 32 mailboxes each), up to 13 SCI channels (with LIN, SPI, and I²C emulation), 4 I²C interfaces (including FM+), 3 RSPI channels, and IEBus. It lacks Ethernet and SDRAM controller - confirmed in Table 1.2 of R01DS0098EJ0180 for the RX631 Group's 100-pin LQFP configuration.

Is the R5F5631EDGFP#V0 qualified for industrial temperature operation?

Yes, the R5F5631EDGFP#V0 is rated for industrial temperature operation from –40°C to +85°C (D version). This rating is specified in Table 1.3 of the R01DS0098EJ0180 datasheet and applies to all RX631 Group parts in LQFP-100 packaging, including R5F5631EDGFP#V0. The device also supports battery-backed RTC operation down to 2.3 V for extended low-power retention.
